I've just discovered someone called Laurence Fox, an actor. The kind of person who might buttonhole you at a party with his intolerant and bigoted views and you make up some excuse like, "sorry, I''ve got to go, I think I have left something plugged in at home". Just as you leave he shouts out to you, "don't get me wrong, some of my best friends are black", and you leave thinking, " yeh, Idi Amin".
